Custom sheet for NSFormatter errors

• Michael Varlik Custom sheet for NSFormatter errors Feb 02 2008, 20:13
  Hi,
  
  when my NSFormatter subclass fails to validate a value the
  -getObjectValue:forString:errorDescription: error method returns NO and a sheet is automatically presented which asks to ether discard the input or accept it.
  How can I replace this sheet with a custom sheet or automatically perform the "discard" action without displaying a sheet at all?
  
  Any suggestions?
  
  Best regards,
  Michael

  Error presentation is performed by NSControl, and is governed by the
  delegate method -control:didFailToFormatString:errorDescription:.  So
  in my mind it would make sense to implement this delegate method and
  have it perform your corrective action.  Alternatively, you can
  override the delegate method to create an NSError with an appropriate
  recovery attempter, and then tell the control to display it.

  I alrady tried to implement the delegate method -control:didFailToFormatString:errorDescription:. With this method I can display a custom sheet, but the other message is also displayed - not as a sheet, but as a modal dialog window.
